Analytical test element with wireless data transmission

Abstract

The present invention concerns embodiments of a system for determining the concentration of an analyte in a body fluid which comprises an analytical test element and an instrument separate therefrom, wherein at least a part of the electrical components of the system are comprised of polymer electronics. Embodiments of the analytical test element comprise an area with reagent chemistry for the detection of an analyte and a transponder configured for wireless transmission of lot-specific data and/or measured values. The instrument has a reading module configured for wireless transmission of data, or data and energy, to the test element and an evaluation unit for evaluating the data or measured values received by the transponder.

1. A system for determining the concentration of an analyte in a body fluid comprising:
 an analytical test element having an area with reagent chemistry for detecting the analyte in a body fluid by generating a measurement signal from the reaction of the analyte with the reagent chemistry; 
 an instrument separate from said analytical test element, said instrument comprising an evaluation unit configured to evaluate the measurement signal and determine the concentration of the analyte in the body fluid, the analytical test element and the instrument being operatively connected in either a contacting or non-contacting manner; 
 
       wherein said analytical test element comprises electrical components at least in part comprising polymer electronics, the electrical components on the analytical test element comprising at least two electrodes in contact with the reagent chemistry and a plurality of galvanically separated electronic circuits and a plurality of parallel transmitting modules configured for wireless transmission of data or data and energy, the instrument further comprising a plurality of parallel reading modules corresponding to said plurality of parallel transmitting modules configured for wireless reception of data or data and energy. 
     
     
       2. A system according to one of the  claim 1 , wherein
 the analytical test element has a memory for storing data. 
 
     
     
       3. A system according to  claim 1 , wherein data which are transmitted in a wireless manner between the transmitting module on the analytical test element and the reading module on the instrument at least partially comprise analog data. 
     
     
       4. A system according to  claim 1 , wherein the analytical test element further comprises a memory for storing data, wherein the memory is writable when the analytical test element is located in a package. 
     
     
       5. A system according to  claim 1 , wherein a transmitting module and a reading module are located on the analytical test element and data or data and energy are transmitted in a wireless manner within the analytical test element between the modules. 
     
     
       6. A system according to  claim 1 , wherein the instrument comprises a holder for positioning the analytical test element.
